IP Core Watermark Technology Protects Chip Designs

July 18, 2008 4:57 am | Product Releases | Comments

Addressing the rapidly-growing international trade in stolen IP, counterfeit chips, and cloned designs, Algotronix has launched DesignTag, a novel concept in tagging using a small low-cost IP core that can be included into an FPGA design or built into a semiconductor. It allows ownership of the design to be positively established and helps in the fight against piracy and fraud. DesignTag is a digital core coded with a customer-specific "signature" that can be identified externally from a working device without needing to read the FPGA bitstream or decapsulate the chip.
